A cohabitation agreement is worth thinking about before you move in together, or as soon as possible after. In Scotland, couples who live together do not get the same automatic protections as a married couple or people in a civil partnership, so it makes sense to sort out what would happen if things change later.
When should you get a cohabitation agreement?
The short answer is: when you are about to move in together, and there is anything financial, practical or child-related that could cause a row later. That might be a property purchase, one person paying the deposit, a mortgage in one name, or one partner stepping back from work for childcare.
Most people are surprised by how ordinary the trigger usually is. It is often not some dramatic event. It is a simple point where you start sharing rent, a mortgage, household bills, or a home that one person already owns. At that stage, a cohabitation agreement can give both of you a clear record of what you intended, which helps avoid a messy argument if the relationship ends.
Why this matters for unmarried couples in Scotland
A lot of people still assume there is a “common law marriage”, but that is not how Scots law works. Living together does not, by itself, give you the same legal rights as a married couple, and that catches people off guard more often than it should. The law does give some limited rights to cohabitants, but they are narrow and can be difficult to rely on in practice.
Under the Family Law (Scotland) Act 2006, the court can consider things like the length of the relationship, the nature of the arrangement and the finances during the relationship. But that is not the same as having a neat set of protections built in. If people want more certainty, a cohabitation agreement is one of the main ways to create it.
What a cohabitation agreement actually does
A cohabitation agreement is a legal document between unmarried couples setting out what should happen to property, money, bills and sometimes children if the relationship breaks down. It can be tailored to your own situation, so it might be simple or fairly detailed depending on how much you own and how you are arranging things.
It is also a way to protect your interests without making the relationship feel formal in day-to-day life. In many cases, couples are not trying to be difficult. They just want to know where they stand if one partner dies, if there is a separation, or if one of them has paid more towards the deposit or the mortgage. That kind of clarity is often the whole point.
Do you need one if you are unmarried?
If you are unmarried and planning to live together, a cohabitation agreement is often worth considering. That is especially true where one partner owns the home, where there is a joint bank account, or where one of you has more assets at the start. An unmarried couple does not automatically get the financial protections that married or civil partners can rely on.
This is where people sometimes rely on assumptions that do not stand up later. For example, one person may think that paying towards the mortgage gives them a bigger interest in the property, while the other assumes all payments are just part of sharing life. A cohabitation agreement can record how this is meant to work before the dispute ever starts.
What about buying a home together?
Buying a property is one of the most common times to make a cohabitation agreement. If one partner is putting in the deposit or paying more of the mortgage, that should be dealt with clearly from the start. It avoids the awkward situation where both people remember the arrangement differently when they separate.
In practice, people often pair a cohabitation agreement with a declaration of trust or similar paperwork if property ownership needs to be set out more carefully. The main thing is to record how this is owned and what happens if the relationship ends. If the home is in one name only, that becomes even more important.
Does living together give you rights?
No, not in the way many people think. Cohabiting couples do not automatically have the same legal rights as a married couple or as people in a civil partnership. That is why the phrase “law marriage” causes so much confusion. In Scotland, there is no such automatic status just because you have lived together for a certain period or for a long time.
There are limited claims available when a relationship ends, but they are not broad, and they are time-sensitive. If you are relying on the hope that the court will sort everything out fairly later, that can be an expensive and stressful way to find out where the gaps are. A cohabitation agreement is usually the simpler route.
What should it cover?
A good cohabitation agreement usually covers the basics first: property, mortgage payments, savings, debts, and household bills. It can also deal with what happens to furniture and other shared items, though people often forget how much those smaller things can matter when emotions are running high. If children are involved, the document can at least flag how financial responsibility is meant to work, even though children’s arrangements are always handled with care.
It can also say what happens if one partner dies without a will, or if one party is paying more into the home while the other is paying in a different way, such as childcare or unpaid work at home. That sort of detail is not glamorous, but it is exactly what prevents confusion later. A cohabitation agreement provides peace of mind because it answers the questions people rarely want to discuss at the start.
Can it be changed later?
Yes. A cohabitation agreement is not meant to sit in a drawer forever while life moves on around it. If circumstances change, it should be reviewed and updated. People change jobs, have children, sell a house, or take on new debts. Any of that can make an earlier agreement feel out of date.
It is sensible to review the agreement if you remortgage, buy another property, or stop working for a while. You can also update it if the financial split between you changes or if the original arrangement no longer reflects reality. The important part is that the agreement still matches what you both actually want.
How is it made legally binding?
A cohabitation agreement is only useful if it is drafted properly and both of you understand it before you sign the agreement. In practice, that usually means getting advice from a family law solicitor who knows what the court is likely to respect and what can cause problems later. It is meant to be a legal document, not just a note between partners.
It also helps if both people get independent legal advice. That is not about making the process formal for the sake of it. It is about reducing the risk of one person later saying they did not understand what they were agreeing to. Family Lawyers Glasgow, like other experienced firms, will usually take that practical approach and make sure the wording fits the real-life situation rather than forcing a template onto it.
When should you ask for advice from a family law solicitor?
You should seek advice as soon as you are thinking about whether you need a cohabitation agreement. That might be before you move in with your partner, when you are buying a home together, or when one of you is contributing more financially. If the arrangement is already in place, it is still worth sorting out. It is better to have clarity late than none at all.
People often wait until they are already worrying about what happens if the relationship ends. At that point, the conversation can feel heavier, but it is still worth having. A solicitor can explain what a cohabitation agreement can and cannot do, and whether anything else should be put in place at the same time. That may include a will or other legal agreements, depending on the circumstances.
What people often overlook, and why it makes sense to make a cohabitation agreement
One thing that catches people out is how quickly ordinary shared life becomes legally relevant. A mortgage, a joint account, money for bills, or a partner moving into a home you already own can all create expectations that are different from what the law assumes. Another common surprise is that the court does not simply treat cohabitants like a married couple if things go wrong.
It is also easy to underestimate how stressful things can become if one partner dies, especially where there is no will. A surviving cohabitant may have some rights, but they are limited and time matters. That is why advice from a family law team can be so useful even when everything feels calm. It gives people a proper plan instead of just hopes.
What cohabiting couples need to remember
- Get a cohabitation agreement before or soon after you live together.
- Do not assume “common law marriage” gives you Scots law protections.
- Deal with the mortgage, deposit, bills and property from the start.
- Review the agreement if circumstances change.
- Get independent legal advice so both of you understand what you are signing.
- Speak to a solicitor early if anything about the setup feels unclear.
Family Lawyers Glasgow regularly helps people work through exactly these issues, and a short conversation now can save a lot of uncertainty later.
